In the late 19th century the luminiferous aether ("light-bearing aether") was invoked as the medium for the propagation of light, when it was discovered, from Maxwell's equations, that light is an [electromagnetic wave]?. By analogy to [mechanical waves]?, physicists assumed that electromagnetic waves required a medium for propagation, and hypothesized the aether. |
